Tuesday April 13th, 12:30-1:20pm – Dr. Zeinab Hosseinidoust
I am a chemical engineer, fascinated by microbiology. For the past 10 years, I have been working on employing the intelligence of biological systems (specifically bacteriophages and bacteria) to tackle the outstanding challenges related to human health. I joined the Chemical Engineering Department at McMaster in July 2016. I am also an associate member at the Micheal DeGroote Institute for Infectious Disease Research, The Farncombe Institute and the School of Biomedical Engineering.
We address the global crisis of antimicrobial resistant superbugs by using bacteriophages, good viruses that are bacteria’s natural predators. These natural antimicrobials can be designed to act as tiny soldiers that only kill the bad bacteria and leave our good bacteria (the ones we need for our health and well-being) intact. We also pack bacteriophages into solid form to design antimicrobial biomaterials, gels and coatings. In addition, because bacteriophages are so good at targeting their prey (bacteria) in nature, we use them to design novel methods of detecting and diagnosing infectious diseases. Our research spans across multiple disciplines and integrates engineering with molecular biology, materials science, and chemistry.

Invited Speakers – Synthesis 2019
Neutrons and X-Rays for Health and Disease Molecular biology is key to understand the origin of diseases and the molecular mode-of-action of drugs, which is essential for modern drug design. Neutron and x-ray scattering are amongst our most advanced tools to study such molecular structure and dynamics. Together with computer simulations they provide unprecedented capabilities in this respect. I will give examples of applications of neutrons and x-rays to better understand the functioning of drugs and antibiotics and how these experiments shed new light on our understanding of cell membrane structure and dynamics, infectious diseases, human blood, and the origin of life, including biomedical applications .
Biography: Maureen MacDonald, is an accomplished professor, respected researcher and the Dean of Science of McMaster University where she is also the director of the Vascular Dynamics Laboratory and is an active member of the Exercise Metabolism Research Group in the Department of Kinesiology. Her research interests are in the area of exercise physiology with specialization in the application of ultrasound techniques to the assessment of the peripheral blood vessels and the heart. She has directly supervised over 100 undergraduate and graduate students and is an expert in cardiovascular health, exercise physiology, spinal cord injury and aging, and leads research into the effectiveness of exercise as a way of preventing illness, improving health status and lifestyle.
In humans, alterations in peripheral artery structure and function play essential roles in the responses of the cardiovascular system to changing stresses. A person’s activity level contributes to both the structural and functional characteristics of their arteries. Understanding the regulation of arterial structure and function is highly relevant given that alterations in blood flow have the potential to influence many other physiological processes in humans. One aspect of my research program has focused on assessing arterial structure and function regulation and adaptation in response endurance, resistance, high intensity interval and isometric handgrip exercise training. These studies have yielded important insights related to the possible labile nature, and regulatory control of some arterial changes with exercise training.
Three objectives for this talk include:
- Outline how exercise can impact blood vessel structure and function and how we can assess those changes in humans.
- Discuss how different exercise prescriptions can result in different impacts on blood vessels in humans.
- Explore the use of acute vascular responses to exercise as an indicator of chronic adaptations with exercise training.
“I’m an iSci alumna, and I’m going to talk about my unconventional experience in graduate school, the best advice I can give to new iSci graduates, and learning by getting your hands dirty. iSci was a challenge and an adventure, and while it set me up for success, it also prepared me for some situations that I hoped to never experience. I’ll also speak about my Master’s environmental science research about climate change impacts on mercury bioaccumulation in sub-Arctic lakes, as well as my involvement in other environmental studies.” (Kyra Simone)

Invited Speakers – Synthesis 2013
Dr. Cecile Fradin
I am interested in studying the dynamics of single molecules inside biological systems using optical tools. Dynamics is essential to the survival of the cell, which is a biological unit in permanent evolution, and which has to be able to process and react to information. Dynamical processes inside the cell happen on a very wide range of length and time-scales, and are governed by complex and intricate rules and mechanisms. At the scale of the molecule, they are of interest for the physicist as well as for the biologist, since they involve basic transformation of chemical or thermal energy into mechanical energy. In order to unravel their exact mechanisms, in vivo quantitative measurements at the single molecule level are required, which recent developments in the domain of fluorescence techniques, single molecule detection, and recombinant protein technology now offers the possibility to do.
